R help - Mar 2009 - dividing ts objects of different frequencies

Hello,

I have two time series objects, 1 is yearly (population) and the other is
quarterly (bankruptcy statistics). I would like to produce a quarterly time
series object that consists of bankruptcy/population. Is there a pre-built
function to intelligently divide these time series:

br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2))
distPop.ts = ts(data=distPop.df[,-1], frequency=1, start=(2000))

The time series I want is:

br.ts[2001Q1]/distPop.ts[2001] , br.ts[2001Q2]/distPop[2001],
br.ts[2001Q3]/distPop.ts[2001] , br.ts[2001Q4]/distPop[2001],
br.ts[2002Q1]/distPop.ts[2002] , br.ts[2002Q2]/distPop[2002],
etc.

This would not be too difficult to write but does anything like this already
exist?

Thank you,

-stephen

Hello,

First, sorry for sending HTML emails earlier. This should now be in
plain-text mode.

I have two time series (ts) objects, 1 is yearly (population) and the
other is quarterly (bankruptcy statistics). I would like to produce a
quarterly time series object that consists of bankruptcy/population.
Is there a pre-built function to intelligently divide these time
series:

br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2))
distPop.ts = ts(data=distPop.df[,-1], frequency=1, start=2000, end=2008)

The time series would consist of the elements (in pseudocode):

br.ts[2001Q1]/distPop.ts[2001] , br.ts[2001Q2]/distPop[2001],
br.ts[2001Q3]/distPop.ts[2001] , br.ts[2001Q4]/distPop[2001],
br.ts[2002Q1]/distPop.ts[2002] , br.ts[2002Q2]/distPop[2002],
etc.

I know that this would not be too difficult to write but does anything
like this already exist?

Thank you,
